v3.0.0-rc2 - Release candidate 2

A number of small improvements since the first release candidate. There were no database changes so you can just overwrite your existing RC1 files with these.

• Changes for better Windows compatibility
• Fix for text fragments containing spaces
• More robust GEOIP2 inclusion
• Remove cases where adding properties to classes would cause an error
• Better timeout detection when running the crawler from the admin UI

Please give this release candidate a try and report any issues back here. Thanks!
